    Centrifugal Pump

    Hey, Glacier........

    It depends on how many kegs you wash at a single time. If you only do one or two at a time in a manual process with short hose / pipe runs (less than 8' - 10'), then a Thomsen Centrifugal Pump will be just fine. Thomsen has straight impellers and though they can move at lot of water at a low head backpressure, they wheeze out around 20 - 25 psi or so line pressure. This may not be enough to spin your sprayers effectively if you have the rotary kind.

    At our fist Brewery, we use a Thomsen Centrifugal Stainless Pump on a 1750 rpm Baldor 1.5 Hp motor. The process is a manual, one keg at a time with a fixed spray wand to clean and sanitize with a single set-up.

    At our second, we'll be washing / sanitizing 4 at a time and will probably use a pair of Goulds Centrifugal Stainless Pumps on 1 hp motors. The Goulds Pumps have a "turbine impeller" and have all teh advantages of a centrifugal pump while delivering line presssures around 60 psi at 3450 rpm. We'll have a wash pump and a water pump. I'm still designing and spec'ing out the hardware for it even while I write this.

    I should add we use Hoff-Sankey Mods and clean through the bung side, so we want a good spray. If you are using straight-side Sankeys yoru pump requirement is different as you want to have a laminar flow along the keg sidewalls and will also want to pulse the stream to clean the keg spear outer surface.


    Anyway, just my $.02, and I'm sure everyone has their favorite pumps and keg washing theories out there.
